' T0 all whom it may concern,.-

Be it known that I, AUGUST FREDRIK LUN- DEBERG, mechanical engineer, asubject of the King of Sweden andNorway, and a resi- 5 dent ofObservatoriegatan 16, Stockholm, in

the Kingdom of Sweden, have invented certain new and useful Improvementsin Apparatus for Manufacturing Carpets or Mats in Through-ColoredPatterns, of which the folxo lowing is a specification.

The extensive use gained by the well-known carpets composed of some corkcomposition and the like has made it desirable to produce such carpetsin through-colored patterns,

I 5 since a carpet of this description does not suffer from the defectcommon to carpets with surface-colors only-viz., that the colors aresoon worn E. This invention therefore relates to an apparatus by meansof which the 2o said throughcoloring of the carpet can be accomplishedin a simple manner, so as to produce aperfectly-clear pattern throughthe entire thickness of the carpet.

It consists of two printing-blocks between 2 5 which the carpet isplaced and which blocks,

both the upper and the lower one, contain depressions or cellscorresponding to the details of pattern and being exactly alike in bothblocks, so as to be directly opposite one an# 3o other when the blocksare placedtogether,

of passages and pipes for introducing the coloring liquids into thecells of the lower block,

of other passages or pipes for introducing air or other suitable gas inthe same cells for dry- 3 5 ing the carpet subsequent tothethrough-coloring, and of means for creating a vacuum in the upperblock, as will be more fully de-V scribed below. In the drawings annexedthe apparatus referred to is shown in Figure 1 in a transverse section,and'in Fig. 2 in a plan view. Fig. 8 is a plan view of'a corner of thelower colorblock, and Fig. 4 is an end elevation of a vacuum-pump. l

1 and 3 designate the two printing-blocks, and 2 the carpet placedbetween them. Both blocks have depressions or cells 4, corresponding tothe pattern required. These depressions or cells are exactly alike inboth blocks', o so that the edges of the cells in one block will beexactly opposite those in the other when the blocks are placed one ontop of the other.

If thecarpet be placed between the blocks andthe latter be pressedforcibly together, there will consequently, owing to the penetration ofthe edges of the cells into the surface of the carpet, be producedclosed chaml v bers 4 on both sides of the carpet, each of said chambersbeing well shut ol from the adjacent chambers close to the surface ofthe carpet in the same block as well as from all the chambers in theopposite block, excepting that directly opposite, which is onlyseparated from the former by the carpet itself. This is of particularimportance for, the purpose in question, inasmuch as when thedepressions of one blockl are iilled with coloring liquid and a suctionis produced in the depressions of the other block the coloring liquid ineach depression will be drawn perpen- 7o dicularly through the carpet.The coloring liquids are, distributed, according to ther patterndesired, in the different depressions of the bottom block, (thereforecalled the colorblock bclow,) the depressions of which, calledcolor-cells,7 are connected either in groups or rows with each otherthrough pipes 5, passages 6 in the block proper, and apertures 7, thelatter located in the bottom of the cells. The pipes 5 issue from therespective color reservoirs. In the pipes are inserted smaller pipes 8,provided with perforations 9 directlybelow the holes 7. The i pipes 8communicate with the pipes 10,which may run together `into one singlepipe. The object of these pipes 8 10 is to facilitate A the emptying ofthe cells and make possible the passage of the adhering coloring liquidinto and through the carpet, as will be more fully explained below. Thecells in the upper block,lcalled the suction-block, communicate with oneanother through holes 15 in the cell-walls, said holesbeing situatedclose to the bottom of the depressions, and consequently at a slightdistance fromr the carpet. There are, moreover, in the cells of theupper block perforated supports 12 for theA carpet. The upper block isconnected with an air-pump throughpa pipe 13. The operation of the`apparatus is as follows: .0n placing the carpet on the color-block andthe suction-block on top of the carpet and on applying a sufficientpressure to both blocks to compress the carpet betweem them the colordIOO ing liquids are introduced into the cells of the color-block bymeans of the pipes 5. The liquids are subsequently made to pass into thecarpet by creating suction in the upper block alternatively whilesimultaneously exerting a pressure on the coloring liquid in thecolor-block. lVhen the coloring-matter has been thus sucked or suckedand forced through the carpet, s0 as to barely appear on the upper sideof the carpet, (for observing which a few glass-covered sight-holes maybe provided on the upper side of the suctionblock,) air is admitted tothe cells of the colorblock through the pipes 8 and lO, and said airpassing upward in the cells through the perforations 9 forms a layernext to the bottom side of the carpet. To admit of this, an ontlet isprovided for the coloring liquid from the cells through the same pipe aspreviously served for supplying it to said cells. To prevent the colorsfrom spattering the carpet when air is admitted, screens ll are appliedover the apertures '7. The suction in the upper block meantime isallowed to continue. At the under side of the carpet there is now noother coloring liquid in contact with the carpet than that which adheresto the surface as a thin film. By the continued suction this liquid isalso sucked into the carpet, being thus kept from spreading on theremoval of the carpet. It is essential that this be done if thecompleted carpet is to present a perfectly clear pattern. The suctionmay be continued until the carpet is perfectly dry, heated air beingsuitably employed for the purpose referred to. The best plan is,however,not to carry the drying operation further while the carpet remainsbetween the blocks than is required for the purpose mentioned above inorder that the blocks may not be engaged longer than necessary. Theoperation described also allows of the treatment of the same piece ofcarpet several times while it still remains between the blocks by theexchange of liquids. For instance,an impregnating material is firstused, then on drying the carpet a coloring liquid, and on a seconddrying another impregnating Huid, dac. On completing the treatment ofone section of the carpet the suction-block is lifted ott and the carpetmoved for treatment of another section, dre.

It is evident that the carpet, fabric, or cardboard after treatment maybe used for various purposesfor instance, as a covering for articles offurniture, as table-covers,&c. also in the making of chess and checkerboards.
